/PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.
18 AWG is recommended for all wires except pin 11, which should be 22 AWG. For 300W configurations 16 AWG is recommended.
There are several ATX variants.
Hope this helps.
If this helps you resolve your problem, please
consider giving me a rating of 4.It will help me as well. Thank you.

Check the label on the power supply for the current rating on 12 volts.
The +12 volt is the yellow colored wire and the black is the ground.
To turn on the switch mode power supply connect pin 14 (for a 20pin connector) or pin 18 (for a 24pin connector) to ground.
You can use a switch so you can turn the power supply ON and OFF.
